ln order that it may he determined from outward appearance Whether ornot the eX- tingri 'eher is charged andreadv for service, we haveprovided means for locking the plunger against returning' to its normalposition after it has been operated, thus holding` the knob, or 'buttonil clos-e to the Cylinder head and indicating` that the device has beenoperated. This may be accomplished in various Ways, but in the presentinstance, we have secured to the Cylinder head above the disk l0 twodepending.,v resilient lingers, 2G, which when unrestrained will divergedownwardly as shown by the dotted lines on Figu l, hut theyv may hemoved inwardly and caused to enter openings in the dish; l0 aud stopperZ when the latter are in their normal positions. 1When the plunger hasbeen moved inwardly far enough to break the container the disk will hemoved liar enough to release the resilient fingers which will spring outof alineinent with the openings in the (liek, hut will lio in the pathof the edge portions; thereof, thus etteetively ,preventing the upwardmovement of the plunger. inasmuch ai; these fingers are inaccessiblefrom the exterior of the casing it is oliviou; that the plunger cannothe returned to ite normal position Without removing the cylinder head.The lingers 2G also serve to lock the disk and the Stopper aggainetrotation.y thus preventie(e,- the die placement o1' breaking; ot thevial in the handlin-g o1 the extinguisher.,
